## Background
FIELD OF THE INVENTION
The present invention relates to a wireless image transmission device, and in particular to a structure that allows a lens body to be separate from and re-mounted to an electronic device, wherein the lens body comprises a transmitter unit and the electronic device comprises a receiver unit so that when the lens body is separate from the electronic device, the electronic device may receive, in a wireless manner, images taken by the lens body.
BACKGROUND OF THE INVENTION
The development of science and technology allows various electronic devices (such as mobile phones, smart phones, and tablet computers) to be combined with an image photographing function, in addition to the ordinary digital cameras and camcorders that are commonly used to shoot pictures or to photograph.
These electronic devices are structured to embed a lens in a device body so that the lens can be used to take images. However, there are drawbacks:
(1) Although the electronic device is provided with a lens, a user must properly hold the electronic device with hands to effect focusing and photographing. This imposes a limitation to photographing distance.
(2) The lens is fixed to the electronic device and is electrically connected a control circuit internally of the electronic device. This makes it impossible to remove the lens from the electronic device.
(3) After being removed, the lens cannot serve as a stand-along device and is incapable of wireless transmission of images.
In view of these problems, the present invention aims to provide a wireless image transmission device that comprises a structure that allows a lens body to be separated from an electronic device and the lens body comprises a transmitter unit and the electronic device comprises a receiver unit so that when the lens body is separate from the electronic device, the electronic device may receive, in a wireless manner, images taken by the lens body.

An object of the present invention is to provide a wireless image transmission device, which comprises a structure that allows a lens body and an electronic device to selectively separate from or couple to each other, wherein the lens body comprises a transmitter unit and the electronic device comprises a receivers unit so that wireless transmission of images can be effected, whereby when the lens body is separate from the electronic device, the electronic device can receive images taken by the lens body in a wireless manner.
To realize the above object, the present invention provides a wireless image transmission device, which comprises a lens body, to which a lens is mounted, the lens body comprising a transmitter unit mounted therein, the transmitter unit comprising an encoder, the encoder functioning to provide an encoded signal of wirelessly transmitted images, the lens body having an end forming a first connection section; and an electronic device, which comprises a control unit and a receiver unit, the control unit being electrically connected to a receiver unit, the receiver unit comprising a decoder, the decoder functioning to wirelessly receive and convert the encoded signal of images from the transmitter unit into a decoded image signal and transmit the decoded image signal to the control unit, the electronic device having an end forming a second connection section, the second connection section being connectable to the first connection section of the lens body. As such, when the lens body is separate from the electronic device, the electronic device can receive images taken by the lens body in a wireless manner.
